Thanks for the maps. This is great! How certain are you of the coordinates for the Texas segment? The Texas Railroad Commission has just made the route available on their public map viewer. I am compiling a list of schools and other senistive areas within a mile of the pipeline.

My data was taken from the RRC’s map viewer in March of this year. There are 462 sample points. Assume some margin of error, but for your purposes it should be fine. TransCanada’s May 30, 2012 Keystone XL permit renewal with the Texas RRC shows no route changes.

Of use to your project might be my mapping of a Voluntary Evacuation Zone, which overlays a 2-mile-wide corridor (one mile either side) along the Keystone XL route. Details can be found here.
